Cannot run Common Lisp code on Jupyter Labs

Question

I just installed the Common Lisp kernel on Jupyter but I cannot run even the simplest function.

For example, when I run:

(+ 2 3)

I get the following error output:

Not sure why it says I have 7 arguments when there are only two.

I followed all the instructions and even installed the zeromq and czmq packages with homebrew.

Any thoughts? Did I miss anything during the installation process?
